vue-treeselect的基本使用以及如何更改id以及label的绑定值-Toy模板网

这篇具有很好参考价值的文章主要介绍了vue-treeselect的基本使用以及如何更改id以及label的绑定值。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

一、最主要的几点就是

1、绑值:value=“form.astdeptId”，主要绑的就是id，通过id找到对应的label回显

2、options是数据源，正常调接口获取就行了

3、append-to-body="true"这个最好加上，可能会遇到下拉的弹窗打不开或者只有一点点高的情况

4、（******） normalizer属性就是把我们自己的后端返的数据格式按树插件需要的格式转换

tenantIdnormalizer(node) {
  if (node.children && !node.children.length) {
    delete node.children
  }
  return {
    id: node.id,
    label: node.name,
    children: node.children
  }
},

5、select点击事件里赋值

6、插槽slot=“option-label” 是下拉框的值

7、插槽slot=“value-label” 是输入框回显的值

二、引入


import XTreeselect from ‘@riophae/vue-treeselect'
// 样式
import ‘@riophae/vue-treeselect/dist/vue-treeselect.css'
